Study Overview
Brief Summary
Depression and anxiety in female patients with cancer are serious comorbidities that affect the quality of life for patients and their survival rates as they have poorer health outcomes. This validation study is a part of the study on the prevalence of depression and anxiety among breast cancer patients. This study aims to investigate the validity of the Kazakh and Russian versions of the Beck Depression Inventory (BDI-II) and Beck Anxiety Inventory (BAI) among female cancer patients in Almaty, Kazakhstan.

Outcomes
Primary Outcomes
BDI-II Score on day 14
Time Frame: Day 14
Beck Depression Inventory (BDI-II) Scale is a 21-item self-reported questionnaire which measures the existence and severity of symptoms of depression. Each of the 21 items on BDI-II tool represents a depressive symptom. The symptoms are each scored on a 4-point Likert scale of 0 to 3 (0=symptom is absent; 3=symptom is severe). Scores for each symptom are added up to obtain the total scores for all 21 items. Total score ranges from 0-63; of which 0-8 is considered no depression, 0-13 is minimal depression, 14-19 is mild depression, 20-28 is moderate depression and 29-63 is severe depression.

BAI Score at Baseline
Time Frame: Baseline
Beck Anxiety Inventory (BAI) is a 21-item self-reported questionnaire which measures the existenceand severity of symptoms of anxiety. Each of the 21 items on BAI tool represents an anxiety symptom. A total score of 0 - 7 is interpreted as a "Minimal" level of anxiety; 8 - 15 as "Mild"; 16 - 25 as "Moderate", and 26 - 63 as "Severe".
ICD-10 diagnosis at baseline
Time Frame: Baseline
The ICD-10 sets criteria for diagnosis of major depressive disorder and generalized anxiety disorder, and will be used as a gold standard of diagnosis of depression and anxiety.
BAI Score Day 14
Time Frame: Day 14
Beck Anxiety Inventory (BAI) is a 21-item self-reported questionnaire which measures the existenceand severity of symptoms of anxiety. Each of the 21 items on BAI tool represents an anxiety symptom. A total score of 0 - 7 is interpreted as a "Minimal" level of anxiety; 8 - 15 as "Mild"; 16 - 25 as "Moderate", and 26 - 63 as "Severe".
Internal consistency of the BAI
Time Frame: Day 14
Internal consistency of the subscales will be evaluated with Cronbach's alpha. Values between 0.70 and 0.90 will be considered good and greater than 0.90 will be considered excellent.
Sensitivity and Specificity of the BAI at baseline
Time Frame: Baseline
Sensitivity and Specificity of the BAI at baseline compared to ICD-10 criteria. Beck Anxiety Inventory (BAI) is a 21-item self-reported questionnaire which measures the existenceand severity of symptoms of anxiety. Each of the 21 items on BAI tool represents an anxiety symptom. A total score of 0 - 7 is interpreted as a "Minimal" level of anxiety; 8 - 15 as "Mild"; 16 - 25 as "Moderate", and 26 - 63 as "Severe".

Test - retest reliability of the BDI-II questtionaire
Time Frame: Day 14
Test - retest reliability of the BDI-II questtionaire on Day 14. Test-retest reliability coefficients vary between 0 and 1, where: 1 : perfect reliability, * 0.9: excellent reliability, * 0.8 \< 0.9: good reliability, * 0.7 \< 0.8: acceptable reliability, * 0.6 \< 0.7: questionable reliability, * 0.5 \< 0.6: poor reliability, \< 0.5: unacceptable reliability, 0: no reliability. On this scale, a correlation of .9(90%) would indicate a very high correlation (good reliability) and a value of 10% a very low one (poor reliability).
